AREA FORECAST DISCUSSION National Weather Service Morristown TN 347 AM EDT Sun Aug 9 2020

SHORT TERM (Today and Tonight). H5 ridging over the lower Mississippi Valley will keep us warm and mostly dry except for isolated diurnal convection this afternoon and early evening. But models are suggesting that a convective system could drop down the northeast side of the ridge out of central KY and into the Plateau before sunrise Monday morning, so attempted to show an early morning increase in POPs very late tonight.

LONG TERM (Monday through Saturday). Overall the upper pattern for the long term period is rather boring, as typically is the case during the summer, with a lack of amplified flow aloft and no real fronts to speak of. Subsequently, local weather will likely be driven by weak disturbances aloft or mesoscale features such as thunderstorm complexes moving in from the northwest. As such, the forecast is a fairly low confidence forecast in general, especially with regards to rain chances. For example, some guidance shows an MCS moving into the CWA from the northwest on Monday but differ greatly on when it arrives (anywhere from just before daybreak to mid afternoon), while others show no MCS but typical diurnal convection.

In general though, warm/moist advection begins during the short/long term transition tonight. And between the potential for an MCS at times, and a weak upper low or cutoff low developing over the central plains Tue night into Wed (drifting eastward into southern IN/IL through the end of the week), a general uptick in convective activity is expected through the week. The forecast reflects this, and favors a more typical afternoon and evening maxima in rain chances through the end of the week, with dwindling PoPs overnight. Timing any MCS activity beyond tonight and Monday morning is next to impossible so stuck with diurnal trends for now.

Temperature wise, expect average or slightly above normal temperatures to continue through the period. This will be especially true in the southern valley where guidance points to mid or upper 90s through much of the week. Perhaps slightly lower readings can be expected for Thu and Fri due to the increase in shower coverage, but even still it will be warm.

Lastly, have continued to undercut most guidance but especially the NBM which is relentless in showing categorical PoPs for days 4 and beyond.

AVIATION. 06Z TAF DISCUSSION.

Expecting mostly fair weather over the next 24 hours. Isolated tstms may dot the landscape again across the southern Valley this afternoon but will not carry a mention at this time for CHA.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
